A practical, step-by-step guide to assembling, applying, calibrating, and tracking penile traction therapy correctly with an FDA-registered Class II medical device.
🔑 Key Facts
- Device standard — SizeGenetics is an FDA-registered Class II medical device manufactured by Danamedic ApS in Lyngby, Denmark, founded 1995.
- Therapeutic tension window — approximately 900 to 1,500 grams-force (9–15 N), reached only after a habituation phase.
- Clinical wear target — 4–6 hours daily (Gontero 2009, PMID: 19138361), usually accumulated through split sessions rather than one continuous block.
- Progress tracking — stretched penile length (SPL) should be measured monthly with a standardized ruler placement protocol in both centimeters and inches.
Penile Traction Therapy Procedure Overview
Penile traction therapy requires a calibrated, step-by-step procedure to deliver consistent mechanical force to the tunica albuginea. Correct technique determines both safety and therapeutic efficacy. The procedure involves six core stages: device assembly, grip attachment, tension setting, session duration management, removal, and daily routine integration.
Penile traction therapy applies controlled mechanical strain to connective tissue through an FDA-registered Class II medical device. Correct technique delivers a reproducible therapeutic stimulus, while poor technique produces unnecessary discomfort, unstable grip attachment, and inconsistent force delivery. SizeGenetics is the FDA-registered Class II medical device manufactured by Danamedic ApS, founded 1995 in Lyngby, Denmark, and this page focuses on the practical use sequence rather than general theory.
📋 Procedure Overview
- Assemble and size the device correctly before the first session.
- Apply the base ring and traction head with stable body-side positioning.
- Set starting tension below the therapeutic tension window during the habituation phase.
- Structure sessions and breaks to build cumulative wear hours safely.
- Remove the device and inspect tissue before the next session.
- Track progress and build a daily routine with standardized measurement and repeatable wear blocks.

Consult your healthcare provider before beginning penile traction therapy.
Step 1 — Device Assembly and Sizing
Device assembly is the first procedural step and the most commonly skipped by first-time users. Correct assembly determines whether the traction device delivers stable forward force or unstable, asymmetric pull. SizeGenetics, as an FDA-registered Class II medical device, should be sized before body application, not while tension is already on the tissue.
Select the correct base ring size
Choose the base ring that fits snugly around the penile base without pressure or circulation restriction. A base ring that is too tight reduces comfort and a base ring that is too loose compromises stability.
Attach the extension bars
Connect the extension bar pair evenly from the base ring to the traction head. Adjust both sides to the same length so the initial setup matches the flaccid stretched penile length without forcing the tissue.
Insert the traction head
Position the traction head or glans cradle squarely at the front of the device. Confirm the comfort pad and contact surfaces are seated level before the device touches the body.
Set the tension spring to zero
Confirm the tension spring is at the lowest setting before device application. Starting with preloaded tension is a beginner error because starting tension must be calibrated only after full positioning.
Verify bar symmetry
Confirm both extension bars are equal and the traction head is centered. Symmetry matters because asymmetric force produces lateral deviation, unstable grip attachment, and avoidable discomfort.
📐 Sizing Note
First-time sizing often requires two or three attempts. That repetition is normal. Spending ten extra minutes on base ring fit, extension bar adjustment, and traction head position improves both comfort and efficacy in every later session. Readers who want the component-specific deep dive should continue to the grip system for penile traction.
Step 2 — Correct Device Application and Grip Attachment
Correct device application, the body-side positioning and grip attachment, determines both comfort and therapeutic outcome. The traction device must sit on the body's natural axis, the glans must be secured without urethral obstruction, and circulation must be checked before any calibrated tension is applied.

Apply the base ring
Slide the base ring to the penile base in a flaccid or semi-flaccid state. Position the base ring flat against the pubic area and avoid catching pubic hair beneath the device.
Extend the penis into the device
Hold the penile extender parallel to the body and extend the penis forward until the glans reaches the traction head. The device application should feel controlled, not forced.
Attach the grip
Secure the comfort strap or noose behind the glans corona, not across the urethral meatus. The comfort strap usually distributes pressure more evenly and is better for beginners, while the noose may suit users who already tolerate grip pressure well.
Confirm alignment
Confirm the traction head, base ring, and extension bar pair remain centered. Reposition immediately if the device points laterally or if the glans sits unevenly in the cradle.
Perform the circulation check
Check glans color, sensation, and temperature before tension adjustment. Normal pink or natural tone, preserved sensation, and absence of numbness indicate acceptable starting fit.

🩸 Circulation Check
Check circulation at zero tension, at initial tension, and again at the 20-minute mark of the first session. Pallor, blanching, numbness, coldness, or sharp discomfort means remove the traction device and refit the base ring or grip attachment.

Step 3 — Setting Initial Tension and Progressive Escalation
Initial tension setting is the most clinically significant setup decision for first-time users of penile traction therapy. The therapeutic tension window for penile traction therapy is approximately 900 to 1,500 grams-force (9–15 N). First-time users should not begin at this range. The first two weeks are a habituation phase targeting 300 to 600 grams-force (3–6 N) to condition the skin, grip interface, and connective tissue before therapeutic tension is applied.
Penile traction therapy works by calibrated tension, not by maximum force. Therapeutic mechanical strain is delivered to the tunica albuginea only when the tension spring is set within a productive range, but that productive range should be entered progressively. Danamedic ApS devices use a tension spring indicator so the user can start low, calibrate sensation, and increase only when the current setting no longer produces mild, tolerable stretch by the 20-minute mark.
| Stage | Tension Range | Duration | Purpose |
|---|---|---|---|
| Habituation (Weeks 1–2) | 300–600 gf (3–6 N) | 30–60 min/session | Skin, tissue, and grip adaptation |
| Entry protocol (Weeks 3–6) | 600–900 gf (6–9 N) | 60–120 min/session | Entering therapeutic range |
| Therapeutic protocol (Week 7+) | 900–1,500 gf (9–15 N) | Per T6 clinical protocol | Active tissue remodeling |
Correct starting tension produces a mild stretch sensation, not burning, sharp pain, or numbness. Increase tension only after the current setting feels neutral by the 20-minute point and only if circulation remains normal. This page covers first-time practical calibration. The full week-by-week escalation schedule, tension parameters, and clinical protocol belong on penile traction treatment protocol. Readers wanting the tissue target behind the therapeutic tension window should also see tunica albuginea and the SizeGenetics medical traction device page.
Step 4 — Session Structure: Duration, Breaks, and Split Sessions
Session duration and break structure are the two most common sources of confusion for first-time users of penile traction therapy. Clinical protocols prescribing 4 to 6 hours of daily wear time do not require one unbroken session. Split sessions can be used to accumulate the same total daily wear time more practically than a single continuous block.
Documented protocols, including 4–6 hours daily (Gontero 2009, PMID: 19138361), should be understood as daily wear hours, not as a requirement for a single extended block. SizeGenetics users generally progress more comfortably by dividing wear time into manageable sessions with a break interval between sessions.
| Phase | Session Length | Break Length | Target Daily Total |
|---|---|---|---|
| Week 1 (habituation) | 30–45 min | 15–20 min | 1–2 hours |
| Weeks 2–4 (entry) | 60–90 min | 15–20 min | 2–3 hours |
| Therapeutic phase (Week 5+) | 90–120 min | 15–20 min | 4–6 hours |

Two or more shorter sessions may be easier to integrate into a daily routine than one long wear block, especially during the habituation phase. A mandatory session break of at least 15 minutes is required after every session to restore circulation, inspect the skin, and confirm the grip interface remains comfortable before wear resumes. Readers wanting the schedule-focused device page should continue to penis extender schedule and wearing routine and penile traction therapy at home.
Step 5 — Removal and Post-Session Inspection
Removal and post-session inspection complete every penile traction therapy session. Correct removal reduces pressure-related irritation, preserves grip comfort for the next session, and helps identify early warning signs before a minor issue becomes a reason to stop therapy.
Reduce tension completely
Return the tension spring to zero before touching the grip or base ring so the traction device is no longer applying active force.
Detach the grip gently
Release the comfort strap or noose carefully from behind the glans corona. Avoid sudden removal that concentrates pressure on one side of the glans.
Remove the base ring
Slide the base ring off only after the front of the device is fully disengaged and the penis is no longer under traction.
Inspect circulation and skin
Check for persistent pallor, numbness, unusual coldness, bruising, or pressure marks that do not resolve promptly after removal.
Pause before the next session
Use the full break interval to confirm normal sensation and tissue recovery before any later session that day.
Brief strap marks may occur after wear, but persistent pain, discoloration, or numbness should not be treated as normal progress. Consult your healthcare provider before resuming therapy if those signs last beyond the immediate post-session period.
Step 6 — Tracking Progress and Daily Routine Integration
Tracking penile traction progress requires a standardized measurement protocol applied at consistent monthly intervals. The clinical standard is stretched penile length (SPL), measured with a rigid ruler pressed to the pubic bone at the same time of day, under the same conditions, recorded in both centimeters and inches.
Measure stretched penile length (SPL)
Apply gentle manual traction, press a rigid ruler to the pubic bone with consistent ruler placement, and record the distance to the glans tip in centimeters and inches.
Measure at the same time of day
Use the same general condition every time, ideally before sexual activity and under similar temperature conditions, to preserve measurement consistency.
Record flaccid length secondarily
Flaccid length is useful as a secondary measure but is more variable than SPL, so SPL remains the primary baseline measurement and monthly measurement anchor.
Measure monthly, not daily
Daily checking amplifies normal variation. Monthly comparison is the clearest way to compare baseline measurement against ongoing tissue adaptation.
Tracking is useful only when the protocol is standardized. A different ruler placement, a different level of manual stretch, or a different time of day can confuse normal biological variation with progress or plateau. Daily routine integration also matters, because a repeatable wear schedule is easier to sustain than improvising sessions day by day. Readers wanting milestone expectations should continue to penile traction therapy timeline.
Common Beginner Mistakes and How to Avoid Them
Six beginner mistakes account for the majority of early discontinuations and poor results in penile traction therapy. Most first-time users do not fail because the FDA-registered Class II medical device is ineffective. Most first-time users struggle because sizing, grip attachment, tension setting, and session duration are rushed or misread.
A base ring that does not fit and an extension bar length that is not symmetrical immediately reduce comfort and device stability.
The habituation phase is required because skin and connective tissue need time to adapt before therapeutic output is pursued.
Glans pallor, numbness, or color change means remove and refit the device before continuing.
A missed session break reduces circulation recovery and increases discomfort without improving results.
Weekly checks confuse normal variation with real change. Monthly measurement gives a clearer signal.
Session sensation reflects current tension setting, not permanent tissue change. Permanent gains require cumulative weeks and months of calibrated mechanical strain.
If any session produces persistent pain, bruising, or discoloration lasting more than 24 hours, stop the session and consult your healthcare provider before resuming therapy. Readers needing full safety discussion should see penile traction therapy safety and is penile traction therapy safe.
Frequently Asked Questions
How long should my first penile traction session be?
The first penile traction session should run 30 to 45 minutes at a starting tension of 300 to 600 grams-force (3–6 N). The first two weeks constitute a habituation phase for tissue and grip conditioning, not a therapeutic phase. Consult your healthcare provider before beginning.
How do I know if I am using the correct tension?
Correct tension produces a mild but tolerable sensation of stretch without sharp pain, burning, numbness, or blanching of the glans. Start below the therapeutic tension window and escalate only when the current setting produces no sensation after 20 minutes and circulation remains normal.
Can I wear a penile traction device during daily activities?
An FDA-registered Class II medical device may be worn discreetly during low-activity tasks when alignment remains stable and the device is not at risk of displacement. Avoid heavy exertion, physical contact, or any activity likely to shift the traction device suddenly.
How do I attach the grip correctly on SizeGenetics?
Position the comfort strap behind the glans corona with the urethral meatus fully unobstructed. Confirm the strap lies flat and applies even pressure across both sides of the glans. Uneven grip attachment is the most common source of early discomfort during wear.
Do I need to see a doctor before starting penile traction therapy?
Consulting a healthcare provider, ideally a urologist, before beginning penile traction therapy is strongly recommended. This is especially important after prior penile surgery, with active Peyronie's disease, or with any vascular or nerve condition. Clinical evidence supports guidance, but medical supervision still matters.
